10 any other source. All of said land is extremely fertile and, when irrigated, will be extremely productive. More than 200,000 acres of said land are owned and held by the State of Arizona. The irrigation of said land will require all of the unappropriated water of the Colorado River and its tributaries, aggregating 9,000,000 acre-feet annually, as aforesaid. Said land, although at present uncultivated and practically uninhabited, will, when irrigated, be capable of supporting a population of more than 500,000, and the irrigation of said land will add greatly to the wealth and taxable resources of the State of Arizona, and to the health, happiness, prosperity and general welfare of its inhabitants. Because of the expense of constructing, maintaining and operating the dams, reservoirs, canals and other works required for the irrigation of said land, it will not be feasible to irrigate said land in small separate tracts, but it will be necessary to combine such tracts into large projects, each project being operated and administered as a single unit. The organization of such projects and the construction, maintenance and operation of such dams, reservoirs, canals and other works will require financing on a large scale, which will be impossible unless water for the irrigation of said land can be appropriated and vested rights to the permanent use thereof acquired at or prior to the time of constructing such works. X In that part of the Colorado River which flows in Arizona and on the boundary between Arizona and Nevada, there are numerous sites suitable for the construction, maintenance and operation of the dams and reservoirs required for the irrigation of the land referred to in paragraph IX hereof. One of said sites is at Black Canyon, on the boundary between Arizona and Nevada.
